The second indicator 112 b may present the current status, such as, “Low”, “Acceptable”, or “High”, of the sensor data in a specific presentation format. The recommendation message 112 c, such as “Hi! Time to change strings”, may present the message based on the analysis of the sensor data. Such display may occur based on the close proximity and/or physical contact of the electronic device 102 to the microsensor 302 of the racquet 304.

In accordance with an embodiment, the processor 202 may be operable to categorize sensor data, such as the tension measurement data, into a first set of sensor data and a second set of sensor data. The first set of sensor data, such as tension data, “X₁” to “X_(n)”, may be associated with a first set of time periods. The first set of time periods may correspond to a set of timestamps when contact of the ball with the racquet 304 is detected.

The processor 202 may be operable to graphically plot the first set of sensor data on the UI 112, such as shown in the graph 308. The graphical plotting may occur for tension data, “X₁” to “X_(n)”, with respect to one or more shots played, such as shots, “S1” to “Sn”. Such shots, “S1” to “Sn”, may be representative of one or more shots played by the player 114 in one or more sports events. In accordance with an embodiment, such representation of the graphical plot may occur based on a preset configuration to graphically plot the first set of sensor data when the electronic device 102 is in close proximity of the microsensor 302 of the racquet 304.

FIG. 4 illustrates a second exemplary scenario for the implementation of the disclosed system and method to process sensor data, in accordance with an embodiment of the disclosure. FIG. 4 is explained in conjunction with elements from FIG. 1, FIG. 2, and FIG. 3. With reference to FIG. 4, there is shown a pressure mat 402, a racquet sensor 404 and a graph 406.

The pressure mat 402 may detect hand pressure exerted by the player 114 on a hand grip of the racquet. The racquet sensor 404 may detect contact of a ball (not shown) with the racquet 304. The graph may be presented on the UI 112. The pressure mat 402 and the racquet sensor 404 may correspond to the sensors 106, as shown in FIG. 1.

In accordance with the second exemplary scenario, the processor 202 may be operable to receive an input, via the UI 112, to graphically plot the first set of sensor data, such as the pressure data, “P₁” to “P_(n)”, and the ball hit data, “H₁” to “H_(n)”. The first set of sensor data may be associated with a first set of time periods, such as time, “t₁” to “t_(n)”. The time, “t₁” to “t_(n)”, corresponds to the time when contact of the ball with the racquet 304 is detected. Such detection may use the ball hit data, “H₁” to “H_(n)”.

In accordance with an embodiment, the processor 202 may be operable to analyze the received sensor data, such as the pressure data, “P₁” to “P_(n)”, and the ball hit data, “H₁” to “H_(n)”. Such analysis may occur by use of an inference engine, such as the inference engine unit 204. In an embodiment, the processor 202 may be operable to graphically plot the first set of sensor data on the UI 112 as the graph 406. The representation of graphical plot may occur for one or more shots played, such as shots, “S1” to “Sn”, during a game play of a sports event. Such a representation of the graphical plot may occur in response to the input provided by the player 114, via the UI 112, to graphically plot the first set of sensor data.

In accordance with an embodiment, the processor 202 may be operable to re-analyze the analyzed data based on a user preference. The user preference may be received from the player 114, via UI 112. For example, sensor data received from the microsensor 302 (as shown in FIG. 3) may be added for additional analysis and/or representation in the graph 406.

In accordance with an embodiment, the processor 202 may be operable to receive input, via the UI 112, to generate one or more recommendations. The processor 202 may be operable to compare the current profile of the player 114 with a historical profile of the player 114. The recommendations may be based on the comparison, such as the comparison of the current profile with the historical profile of the player 114 or other profiles of other players.

In accordance with an embodiment, the recommendations may be value-added information, such as, “You played a total of eighty shots in last game”, “Pressure on the hand grip of the racquet during first ten shots detected very high (above <threshold value> and/or based on the previous sports events)”. The recommendations may be suggestions, such as “Hold the lower part of the hand grip of the racquet for optimum performance during start of the sports event”. In an instance, the recommendations may be a display message, presented at a predetermined portion of the UI 112. In an instance, the recommendations may be an audio output, generated by an output device, such as speakers.

FIGS. 5A and 5B collectively represent a flow chart 500 that illustrates an exemplary method to process sensor data, in accordance with an embodiment of the disclosure. With reference to FIG. 5, there is shown a flow chart 500. The flow chart 500 is described in conjunction with FIGS. 1 and 2. The method starts at step 502 and proceeds to step 504.

At step 504, sensor data may be received from the sensors 106 associated with the item of sports equipment 116. At step 506, the received sensor data may be analyzed. At step 508, the received sensor data may be categorized into a first set of sensor data and a second set of sensor data. The first set of sensor data may be associated with a first set of time periods and the second set of sensor data may be associated with a second set of time periods. At step 510, the received sensor data may be compared with one or more predetermined threshold values.

At step 512, a current profile of the player 114 may be generated based on the first set of sensor data. At step 514, the current profile of the player 114 may be compared with a historical profile of the player 114. The current profile of the player 114 may be further compared with a pre-stored profile of another player. At step 516, one or more recommendations may be generated based on the analyzed sensor data.

At step 518, the generated one or more recommendations may be displayed. At step 520, an input may be received on the UI 112, to graphically plot the first set of sensor data for one or more shots played. The first set of sensor data may be displayed on the UI 112. At step 522, the first set of sensor data may be graphically plotted on the UI 112 for one or more shots played. At step 524, a user preference may be received on the UI 112, to re-analyze the analyzed data. At step 526, the analyzed data may be re-analyzed based on the received user preference. Control passes to end step 528.
